In the'illustrated embodiment ofmy i ventionl have'shown the same applied to a` i `cabinet lhaving an` upper compartment 2 closed by apair of 'swlnging'doors 3 ande, j

the free edge ofone'of the doors being pro-` vided with a bead' to lap over` the free edge l 0 ofthe other door when said doors are closed,

`whereby through the latching of one door both doors `maybe held latched. The cabi` i net is'also provided at its'baseiwith 'a single wide lower drawer 6 and a pairof narrowerl r f' upper drawersk 7 and 8,`the said :drawers y7 and 8 being arranged side by'side andin parallel relation to each other. j

*eXteriorly projecting handle or operating member 22 is provided.for'rocking'thelever of' the inner end of said lever. suitable 16, and by manipulating this operating membervso-as to `torce theinner'end of the leverj16 downwardlyjthe lower bo'lt or latch 11 will be withdrawn fromflatching engage ment. with its keeper, and upward movement'y willbe simultaneously transmitted .to the rod 14, which in turnvwill rock the rlever 15, movf ingthe jointed ends' of the levers'l andf 19 downwardly and thereby moving the inner fend of thelever 19j upwardly to withdraw the upper bolt or latch from engagement with its keeper, leaving the doors 3' and 4 free to be opened. The rod or -bar 14 is norv mally-sustained andthe parts of thelatching mechanism referred to maintained in normal latching position bymeans of a spring actuated'slide23 mounted in a'guideway 2401i the top of the cabinet, said rod or bar being connected at its upperend with the slide means of a cord or other flexible connection irunning in contact wi-tha guide pulley 26.' Thep`ull ofthe spring 27 actingf on the slide -23 tends to support the rod 14 Aand opl poseandlimitits downward movement under the action of a-spring-28 connectingrthe lower end fof tlieV rod 14 with :the cabinet body,q which spring 28 draws the red 14.

Pivo'tally attached to the opposite end of the bar 36, at its upperend, as indicated at 4-1, isa lever 42 intermediatelyrfulcrumed upon the cabinet, as indicated at 43.' 'Thelower Vend of this lever 42 isjiointed, as

at .44, -tol theupper end of a cooperating lever 45 vlulcruined upon the cabinet at an intermediate point, as indicated at 46,'said lever 45 being ulcrumed at its lower'end Vto the sliding latch bolt 35. The two levers42 v and 45 are mounted to swing onV their inlcrum'stransversely of the cabinet body and are *normally arranged at an angle with their Vjointed ends projecting outwardly and said levers out of alinement with each other.

Solv

When the'bar ois movedV from its normal position toward theright hand side of the cabinet, the upper ends of the levers'39 and 42 will be swungoutwardlyorin the same direction as the bar, while the. lower ends of saidlevers willbe swun V,inthe reverse direction or outwardly. y lever/39 .will 'be actuated to withdraw the latch bolt 341dire`ctlypA from its keeper 32,

yfthisj means the whi'l'eithe lever4 42 willv be actuatedto move ftheupperendof the lever 45 inwardlyand thejlower Aend of said lever 45 outwardly,

thus withdrawing'thelatclh bolt 35 Yfrom engagement ffwith its keeper'. The, drawer`6 will thereuponbe free forjopening movement under thea'ction of thespring 31,1such .Y f movement being vlimited byl the stops 33.

Then the operatingdevice'BS is" released after actuationof the lever 36 in thejmannerdescribed, a spring 37Y will'r'eturn the bar 36 andflatch actuating levers back to normal position. The latches 34 areprovided 'with beveled endsf -SOthat when Ythev if drawer is moyed'inwardlysuch bevelede'n'ds will allow 'the latchesto4 be retracted suiiiiently toaride lin contact with wear strips 46' upon A'thesides of the drawer untilsaid Y latches come -in'to register with the keepers 32, whereuponthe latchesjwill snap into en` gagementfwith Vsaid)keepersiand: lock'the Vdraw'rfi infclo'sed position.V

Thealmas` rami-s are moan-fea to 'Slide onfsuitable guides y47 andaspringor springs 48,; c0in'lootingfeachy drawer with the cabinet drawer. automatically 'to open position when drawer `is providedV ongitsf undersideiwith alreeper 49', astofp 50, and a wearV strip 51v Vsimilar to [the :corresponding Vparts on j, the

drawer 6,VV the "keepers on the respective body, is` or Aare provided 'i'or moving theV the drawerl is unlatched. EachV upper# Y,

drawers 7 and 8 ybeing respectively adaptedV latch bolts 52 and53. The Vlatch bolt 52 is pivotallyV coupled toa horizontally we z'z'tend-V ing vlever 541intermediately fulcrumed upon the casing, -as at 55, and Apivotally coupled at its 'opposite 'end by meansA of a linlr56jto @aan an anteilig dlievii? irremedilor cooperation Awith verticallyinnegable v` teriorly projecting handle orfinger piece 59 whereby it may be manipulated. A spring 60 connects the latch carrying end of the lever 54 with oneof the'guides and holds such end of thelever normally elevated to maintain the latch bolt 52 in latching position. Upon depressing the operating element 59 the linlr`56will be drawn upward to tilt the latch carryingend of the lever 54 downward against the resistance of the spring 60, thus retracting the latch bolt 52 and releasing the drawer ,7 for opening movement. The latch bolt 53 is pivotally connected with one end of an.` actuating lever 61 fulcrumed intermediately upon the cabinet body, as at 62, thexlatch` carrying end of said lever 61 being normally held elevated by a latch projecting spring 63. The opposite end of said lever 61 is pivotally coupled to the forward end of a trip lever 64 intermediately fulcrumed upon the cabinet as at 65 and jointed at its opposite end, as at 66, to the forward end of a second trip lever 67 intermediately fulcrumed upon the cabinet body, as at 68. The rear end of the lever 67 is normally arranged to rest upon the laterally projecting finger 69 of the upbent spring arm-70 of a latch -trip spring 71 having its other arm 72 suitably secured to a portion of the cabinet.` The` arm 'Z0 of the spring 71 is disposed in the path` of sliding lmovement of the part 67, so that when said part isinoved inwardly and held in latched position the spring arm 70 will be depressed by the weight thereof. `When the spring arm 70 is depressed the levers 64 and 67 are arranged in substan-` tially longitudinal alinement, inwhich position they are maintained by the action of the spring 63, which under such conditions maintains the latch 53 in latching engagement to hold the drawer 8 from opening movement. When however the latch 52 is retracted and the drawer 7 moves to open position and out of engagement and in advance of the spring arm 70, said arm is free for actuating movement and swings thc rear end of .the lever' 67 upwardly. The spring 70 is of a strength sufhcient, when released, to overcome the resistance of the spring 63, and as a result of such move` inea .bene-'52 eea 53 have beveiea ende te ride iii contact with the wear strips 51 to l ysaid keepers and latch the drawer in closed position.- It rwill thus be understood that uponY the closing of the drawer 7 said `drawer will lbe latched by its latch bolt 52 and the drawer will come into engagement `-with thetrip spring 70l and set'the tripv mechanismof the latch bolt53 to adapt said latch bolt for latchingengagement with the drawer 8 when .the latter is closed, in which operation they actuating lever 57'will i ybe returned to normal position.

l Itvwill `be evident `from the Jforegoing description that my invention provides a cabinet structure' having a plurality of closures adapted to be latched without the use of a key and to beopened in a ready and convenient manner, the kconstruction also being such that an automatic'ropening movement of certain closure members is obtained upon therelease of the same for opening' manipulated only by a person familiar with their location and method of operation, so that if desired a cabinet may be provided with closures which when latched will be proof against opening movement by any f opening the closure when released for opening vmovementj two independently pivoted jointed levers, a latch connected with one of the levers for latching the closure in closedk position, yand actuating means connected with the other lever.
